Be it known that 1, ROBERT J. LA RUE, a citizen of the United States,residing at Mexice, in the county of Audrain and State of Missouri, haveinvented certain new and useful Improvements in Annunciators orSignaling and Registering Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, whichwill enable others skilled in the art to which it up pertains to makeand use the same, reference being had to the accompanying drawings,which form a part of the specification, and in which- Figure 1 is aperspective view of my improved annunciator or signaling and registeringapparatus, showing the connectingwires broken off. Fig. 2- is a frontview of as much of a window frame and sash as will illustrate thealarm-operating mechanism, parts of the frame and sash being broken awayto show the operating mechanism, and the wire being shown extended, soas to have its broken end register with the broken end of the wire infollowing Fig, 3, which is an end view of the apparatus, showing thehinged sides of the casing swung down and the alarm given. Fig. i is afront view of the open casing, showing the mechanism. Fig. 5 is a topview of the casing, and hig. 6 is an end view of the closed casing withthe end piece removed.

The same letters of reference indicate the same or corresponding partsin all the figures.

My invention has relation to annuncia-tors or to apparatus for signalingand registering an alarm at a centralstation by means of wires beingshortened or drawn at the points at which the operating mechanisms areplaced; and it consists in the improved construction and combination ofparts of such an apparatus, ashereinafter 'iorefully described andclaimed.

The registering and sounding mechanism consists of a casing having itsback 1 secured to the wall or any other suitable vertical surface, andhaving a top, 2, rigidly attached to its upper edge, and a bottom plate,3, and a front plate, 4, hinged to the lower edge of the back and toeach other, unfolding when released, A long box, 5, is secured to theforward face of the back plate, and the ends of this box are formed withbearings 6, in whic a rod, '1' having a squared end, 8, may turn andslide. This rod is formed with a wide and short bail, 9, having its endspassing through L-shaped slots in the front of the box into the rod,where they are secured, and a spring, 10, serves to force the rodendwise, pushing the squared end toward the end of the casing. The bailslides in the horizontal branches of the L-shaped slots with its arms,and the rod may be pushed into the box and have the arms of the bailturned up in the vertical branches of the slots by a suitable key, 11,fitting upon the squared end, or by any other suitable means, thetension of the springbeing so stored that it will force the rod outwardwhen the arms of the bail are released from the vertical branches of theslots.

A number of arms, 12, having eccentric cam-heads 13 at their inner ends,are pivoted at the inner ends upon a rod, 14, above the I L- shapedslots, being spaced by suitable tongues, 15, and extend horizontallyoutward, having their eccentric heads bearing against the long end pieceof the bail when the latter is turned up, so that they will tilt it downwhen their outer ends are drawn up.

. V-shaped springs 16 are secured to the top of the casing and to thearms, keeping their outer ends down, and rods 17 are pivotally connectedwith their lower ends to the outer ends of the arms and have their upperends bent back and down to form eyes 18 at the upper ends anddownwardly-facing shoulders or catches 19 a slight distance below theeyes. The upper portions of the rods pass up through a longitudinalslot, 20, in the top of the casing, and this slot is covered with aplate or strip, 21, having notches or transverse slots 22 in one edge,through which notches or slots the rods may proj ect and slide.

A plate or strip, 23, is hinged upon the top of the casing with its freeedge overlapping the slot in the top, and spaces are marked upon thisplate corresponding to the slots, each space having a number, and theshoulders or catches of the rods may engage the free edge of this platewhen they are raised, the shoulders or catches resting in the spacehaving the number corresponding to the number of the wire, 24, which isdrawn, the said wire being secured to the upper end of each rod andpassing over suitable supports to the operating mechanism having thecorresponding number.

The numbered index -plate is preferably hinged by having two pintles,25, at its ends journaled in suitable eyes, 26, upon the top, and one ofthese pintlesis preferably provided with a suitable thumb-piece fortilting the plate.

A latch-spring, 27, is secured to the top of the casing, and has asuitable notch or shoul' der, 28, at its lower end, which may be engagedby a latch-stud, 29, upon the bottom plate, the said spring serving toengage the stud and to hold the casing closed, and the spring is solocated within the casing that the hail of the sliding rod will strikeit and disengage it from the stud when the rod and bail are released,allowing the bottom and front plates to unfold.

At the end of the casing, opposite to the squared end of the rod, is aclock-work, 30, having a hammer, 31, vibrated by the same and striking abell, 32, in the casing, and the end of the sliding rod will bearagainst a stop, 33, in the works, preventing their revolving, butallowing their revolving and the sounding of the bell when the rod isreleased.

An arm, 34, having a socket, 35, for holding a match or fuse, 36, uponits outwardly-curved portion, is pivoted at its upper end to the back ofthe casing, and has its lower end pivotally connected through aconnecting-rod, 37, to a rod, 38, pivoted at its lower end to the frontplate, and the match-socket is so located that when the bottom and frontunfold the lighted match will be brought to register with the burner ofalamp,39,pivoted in brackets 40 upon the bottom, so that it maylight it.The match comes in frictional contact,as itis drawn downward by the armsunfolding,with a segmental friction-face, 41, projecting from a shaft,42, pivoted in vertical bearings, and this shaft is provided with astud, 43, projecting at right angles to the friction-face and in theline of the squared end of the sliding rod, so that it may be struck bythe said end of the rod when the latter is released, and thus revolvethe shaft to bring the friction-face within reach of the match, whilewhen the rod is forced in again and set the friction-face may be foldedback, so that a new match placed in the socket will not strike the facewhen the bottom and front are folded up and the apparatus set foranother alarm.

It will thus be seen that the casing will be opened and the lamp lit andthe bell rung whenever a wire is drawn, raising the corresponding rodsufficiently to tilt the bail of the sliding rod and to cause theshoulder to engage the index-plate, and the number of the wire andconsequently of the place from which the alarm is given may be read byreferring to the space of the index-plate engaged by the shoulder.-

The alarm operating mechanism which I use with windows or doors consistsof a pul- -to the frame, serving to return the pulley to its orignalposition when released. The sash is provided at its edge with along'narrow box, 50, in the open side of which a block or strip, 51, ofrubber or similar elastic material, is secured, and this strip will comein contact with the periphery of the pulley and revolve it,

winding the wire upon the pulley whenever the sash is raised.

When the device is applied to a door or to any hinged or swingingobject, the pulley is so placed that its periphery will be engaged andthe pulley revolved by a strip upon the moving edge of the door or otherswinging ob ject.

Having thus described my invention,I claim and desire to secure byLetters Patent of the United States- 1. In a signaling and registeringdevice, the combination of a pulley j ournaled in the window-frame, withits periphery projecting into the way of the sash and having one portionof its periphery cut away, and having a spring for returning the pulleyto its original position, a cord or wire extending to the signalingapparatus and winding in the grooved periphery of the pulley, and a longbox upon the sash, having an elastic strip secured in it engaging theperiphery of the pulley, as and for the purpose set forth.

2. The combination of the casing having the downwardly-unfolding bottomand front, the sliding belt or rod having means for releasing andsliding it and having means for releasing the bottom and front, the lamppivoted between brackets upon the bottom, the matchsocket upon the armpivoted to the'back of the casing and pivotally connected by aconnecting-rod to the rod pivoted to the front, and the shaft verticallypivoted and having the friction-face projecting from it and the studprojecting from it at a right angle to the frictionface and in the lineof the end of the bolt or rod, as shown and set forth.

3. The combination of the casing having the folding bottom and front,the box having the bearings and the Lshaped slots, the sliding rodhaving the spring for forcing it to one end and having the bail with itsarms projecting and sliding in the slots, the spring-latch upon the topof the casing and the stud upon the bottom, and the cam-arms havingtheir heads bearing against the raised and set bar of the bail andhaving springs forcing them down and rods for drawing their outer endsup, as shown and set forth.

4. The combination of the casing having the folding bottom and front,the box having the ICC bearings and the L-shaped slots, the sliding rodhaving the spring and the long hail, the cam-levers having the \l-shepedsprings, the rods at the ends of the cam-levers, having the eyed endsand the shoulders, the notched plate over the slot in the top of thecasing, the pivoted plate upon the top of the casing, the latchspringupon the top of the casing, the stud upon the bottom, the alarm-workshaving a stop engaged by the end of the set sliding rod or bolt, the lamp suspended between the brackets upon the bottom, the arms pivoted
